Author's notes:

It occurred to me that we don't know much about Kono's personal life, and coming from the rough world of cops, she would a protective sister when it came down to it. I'm think of putting this as 4+ chapters so bare with me because there's a lot of stories about Kono's past that I'd like to write too. Read, Enjoy and Review! My first fanfic so please be nice :D

The team was all sitting around in a bar toasting their success in yet another case. Danny decided to go first

"Ladies and gentlemen, and Steve (the team groans in unison at Danny's dry joke) let us drink to yet another case well done. From Kono's roundhouse kick to Steve's recklessness, we're one well oiled team! Cheers !"

"Cheers!" the team said in unison.

The team was happily reminiscing about their various antics when a very distressed teary girl approached their table

"Kono? Oh my God Kono… I'm so s-s-sorry... I couldn't do any-y-ything… they just took her.."

Steve was the first one to respond

"Kono who is this girl?"

Kono ignored Steve but she turned to the girl with a very worried expression

"My sister? What happened to her? Lani what happened?" She said in a distressed tone.

"They just took her kono… we were out the back of the club… a-a-and they just t-t-took her. There were like more than 6 guys… I couldn't do anything… I'm so s-s-sorry Kono… I should've done something." The girl just kept going on crying and apologising to Kono

"WHAT? Take me to where she got taken now. (Turns to the team) guys please I need your help."

The team stood up without saying anything and followed the girl to the back of the club. From there Steve took control

"Chin, contact HPD and tell them to get a crime scene team down here ASAP, Danny go inside and get the security footage from that camera (points to the security camera, and turns to Lani and Kono)

"I know this is hard for you but can you tell me exactly what happened?"

"Well.. she wanted get some air after she turned down about 7 sleazebags on the dancefloor alone so I came with her outside, we were outside when those guys in black came up to her grabbed her, she tried to fight them off, she downed about 5 of those guys before one of those guys took her out with a stungun… Holy shit I can't believe I didn't do anything Kono… one of those guys just grabbed me and wouldn't let go… Kaila fought off all of them… and I couldn't do anything…"

Kono felt so worried about her sister right now, but she had to comfort Kaila's friend, it's what a good cop does.

"Ok listen to me, you see those officers in uniform? I want you to give them your statement about what happened, and Chin's arranged for one of those officers to take you home. Once you get home I need you to stay home until I call you."

Kono wiped Lani's tears away and Lani walked to the officer to give her statement. She turns to Steve with a heartbreakingly desperate look on her face, and Steve could not help but pull her into a hug.

"Listen to me Kono, your sister's gonna be fine. If she can fight off 5 probably professional kidnappers, then I have a strong feeling she can handle whatever she's got coming. Plus, she's your sister, that means she is a very tough girl. Kono (makes eye contact with her) I promise you we will find her."

Steve delicately wipes Kono's tears away and gives her a rarely gentle smile, and Steve's heart starts pounding when Kono gives him a sweet kiss on the cheek.

"Thanks boss. She's tougher than me to be honest."

"Then she must be a wall of diamonds. Let's go back to HQ and review the security footage."

"Sounds good brah." Kono smiled bravely.

Danny and Steve are driving back to HQ

"So Steven, you still seeing Catherine?"

"No I broke it off because she's never gonna be looking for something serious with her job and all, plus I've got feelings for someone else."

"Who Kono?" Danny said with a smirk

"Why do you always think I like Kono?"

"Because partner, you may be good with firearms but hiding your feelings isn't a Navy SEAL's strong suit."

"Well you can forget the whole "Why haven't you told her" lecture, Cos there's no way I'm gonna tell her."

"Steve look, Kono gets asked out probably at least 10 times a week by multiple men, and plus there's Charlie Fong. She's not gonna be on the market forever."

"Since when were you such a cupid Romeo?"

"Ever since I met you babe, now strap on a pair and ask her."

"Stop nagging me like you're my wife Danno."

"Not until you divorce me Steven."

Steve was deep in thought, what if Kono is off the market before he gets a chance to ask her? But if Kono shoots him down and their friendship can't recover? His taskforce needs Kono.

Back in HQ

Danny pulled the footage from the club and pressed play

It shows basically exactly Lani says, Kono's sister fights off 5 guys who looks like professional hitmen before getting popped by a stun gun. Danny and Steve just stared at the video in awe. Never had they seen such an amazingly skilled girl in their lives. Sure Kono was a very skilled woman, but her sister… and she's still very young... Kono and Chin were really amused by those two's reactions

"Brah, this is kinda insulting to me"

"Well Kono we all know where she gets her skills from, but how did she get so good at hand to hand combat? At such a young age?"

Kono's reaction was not expected by Steve and Danny, her face turned white and wouldn't make eye contact.

"Uhm, can we drop this and focus on the case please"

"Kono..? what's wrong? How did she get so good at hand to hand?"

"Danny just drop it." Her voice was so sharp and her face was so alike Steve's aneurysm face that it sent a chill down Danny's spine. Luckily Chin soon spoke to break the tension

"So looking at the footage, they're wearing gloves so we won't get any prints off the scene, but I did manage to get 2 clean shots of 2 of the kidnappers. I ran them through every facial recognition database that I could find, and I got hits. The two kidnappers goes by the name of Diego Sanchez and Kaleo Kaluhiwa. They're known to go the dirty work all over the island for anyone who can afford it, and they're the best at what they do."

"Evidently, ok so we got a location on these two? (Chin nods) Me and Danny will go and pay those two a visit while you and Kono go through Kaila's phone records, and any sort of communication system she uses got it? Don't leave anything to chance, there has to be a reason she was targeted."

Everyone began to move when Steve pulled Chin back

"Chin why did Kono avoid Danny's question earlier?"

"Brah you want me to snitch on my cousin? She'll rip my face off."

"Chin please, you know I only care about her well being."

"Alright. Kaila's like this because of an incident that happened a few years back when Kono was still on the circuit. At the time, Kono had a boyfriend called Adam, whom she thought was "The one". Kaila thought Adam was perfect fit for Kono until one night, Adam raped Kaila."

"WHAT? Did Kono bash the shit out of that bastard?"

"No that's part of why Kono feels so ashamed and guilty. She chose to believe Adam instead of her own sister, thinking her sister was just trying to sabotage her relationship. In spite of that Kaila knew she had to do something to get Kono out of the relationship before Kono was assaulted too. So she said some stuff which provoked Adam to assault her viciously. She didn't think that he would take it too far, but she was injured so bad that she never got the chance to be on the pro circuit like Kono, and she more potential than Kono. She was supposed to be signed on to Ian Adam's surfing company in a week. She had a bruised face, fractured skull, broken arm and three broken ribs, a collapsed lung and a broken leg. Basically she was dead, but Kono found her just in time and the paramedics saved her from the brink of death.

"Wow was Kaila angry at Kono?"

Even then Kaila was never angry at Kono, which only made Kono more guilty. HPD managed to find Adam after a few days, and Kono stayed by her hospital bed everyday until she was discharged, and helped her with the rehab and everything. Kaila never felt so helpless in her life so she took it upon herself to learn every and anything to do with hand to hand combat and self defence. She learnt from the island's leading martial artist Mark Dacascos and even went to the mainland for a month to learn Jiu Jitsu, Judo, Kung Fu etc. It took about 2-3 years of constant lessons, practice and gym, she went through so much pain just to make sure she would never feel that helpless again, she was obsessed. But the one that felt the worst about all this was Kono. She had caused her sister so much pain because she didn't believe her Ohana. Because of all the constant martial art lessons and such, she lost a lot of her friends, she was a social pariah at school. It's part of why she believed in me through the whole forfeiture locker ordeal, because she knows now how important it is to believe your Ohana, and because she knew that the loneliest place on earth is where no one believes you. Kono has tried not to talk about it ever since, but if Kaila gets killed, Kono could never forgive herself, and neither could I. That's why we have to get Kaila back, She's my and Kono's family Steve, we would gladly sacrifice our lives for her."

"Chin, you know I would die for any of you guys at Five-0, and I would die for your families too. Grace, Rachel, Malia, Kono's parents, Kaila. If they're your family, then they're my Ohana too."

"Thanks brah, means a lot y.."

"STEVEN, do I need to put a leash on you and drag you around?"

"Shut up Danno. Get on it Chin, we gotta find Kaila, so we start by finding these son of a bitches."

Danny and Steve are driving to Diego and Kaleo's locations, while Chin and Kono are back at HQ digging up Kaila's phone records and computer history.
"So Steven, what's your weapon of choice if they don't give you information today?"

"I'm a Navy SEAL Danny, I'm gonna do it the SEAL way."

"Oh yea? What way is that? I'll blow your door open if don't give me information? I'll ride a motorbike up your stairs? I'll throw you into a shark cage if you don't co-operate?"

"Danny I'm a NAVY SEAL, I can't and I won't change my ways."

"I'm just saying tone your ways down. I'm not saying that your way is wrong, no, I'm saying your ways are COMPLETELY INSANE. You store anymore grenades in the back of my trunk and in your bedroom drawer I might have to arrest you on suspicion of terrorism Steve."

"You know what Danny? Let's just not talk at all, because my head might explode like a grenade if you continue talking."

Danny and Steve arrived at where Diego and Kaleo are know to hang out at.

*knock* *knock* "Diego Sanchez and Kaleo Kaluhiwa, Five-0, we need to talk."

"Five-0 Open up."

Steve took a few steps back and took a run up and kicks open the door. Inside they find multiple firearms and Diego and Kaleo standing behind steel doors.

"Diego and Kaleo we're just here to talk, open that dam door."

"Yea or Mr Slaughter here will have to grab you the hard way, your choice."

"We ain't opening no doors brah, you don't have a warrant."

"Oh yeah? Watch me."

"See what you two have done? Now he's gonna go, and probably get some sort of weapon and potentially blow all of us to pieces."

Steve went back into the car to fetch some of his grenades.

"Steve I am begging you, please think about what you're doing and the level of risk using a grenade is."

"No sweat Danno, I got this."

Danny shakes his head

"Clearly."

"Ok last chance you two, if you don't open up, I'll just have to blow your door open."

"Asif brah, you're a cop, you won't do nothing."

"Alright well your funeral."

Steve straps two grenades to the steel doors and motions to Danny to get out, pulls the pin and sprints behind a wall.

BOOM,, the door flies off and the two suspects gets knocked over. Danny quickly hand cuffed both of them.

"Let's all take a trip to the slaughterhouse shall me?"

"Book 'Em Danno."

"Are you kidding me? You're gonna start that again?"

"Like it or not Danno, its catchy."

"Shut it you."

Steve smiled and turned to Diego and Kaleo

"And just for the record, I'm a Navy SEAL, not a cop."

Steve and Kono are in the interrogation room because Kono had insisted on grilling those bastards for information herself.

"Ok so here's what's gonna happen. You give us information, and we can lower your sentencing. You give me what I want, and I'll help you."

"We ain't giving you nothing, this client is different brah. If I tell you anything he's gonna wipe out my entire family."

"Okay you give me the location of my sister right now and I'll play nice, if you don't, I'll wipe out your family myself." Kono said menacingly.

Steve saw that Kono was about to snap and do something to Diego and Kaleo so he quickly stepped in.

"I'll place your whole family under protective custody, I'll do whatever it takes to protect them, but you gotta give me a name, a location. EVERYTHING that you know about this client of yours and where Kaila Kalakaua might be."

"No way this guy will wipe out my family before you even get to my family, he got contacts in HPD brah."

"You forget who I am, I'm not a cop, we're the governor's taskforce, we don't go through the system. Now you give us what we want, or I'll send out a message to HPD that you ratted out."

"…. Alright brah. But this isn't your usual criminal. This guy is the mastermind behind it all brah, we've heard about him killing off whoever might be a threat."
"Okay give me a name, something!"
"We weren't told much, we were just told to work with the other professional hitmen and kidnap the girl and bring her to a location and dump her into a white van. There wasn't a plate number on the vans. But I recognised from of the guys from the Yakuza (Steve and Kono's faces turned pale white at that revelation). The guy who hired us goes by the name of Wo Fat.

I wanted to end the first chapter as a cliff hanger because there was a lot of information in the first chapter and I had to put some excitement into the chapter. Review please
